The CHART system strives to manage freeway and
arterial traffic flows with the goal of greater
efficiency and safety. When freeways and other
primary
routes are unexpectedly congested, some
traffic will shift to surface arterials. Arterial
signal systems are being installed statewide to provide
remote and adaptive traffic signal control and
coordinated signal timing. Traffic signal technicians
and CHART system operators can better balance demand and
capacity by adjusting traffic signal
timing remotely.
